Joint NEA project performs high-burnup test
An article in the OECD Nuclear Energy Agency’s July news bulletin noted that a first test has been completed for the High Burnup Experiments in Reactivity Initiated Accident (HERA) project. The project aim is to understand the performance of light water reactor fuel at high burnup under reactivity-initiated accidents (RIA).

Two reference operational scenarios for the ITER CDA design are examined with the time-dependent 1½-D WHIST transport code: the A1 ignition case and the B1 long-pulse case. Plasma profiles are evaluated self-consistently from the source profiles and radial-dependent transport properties. Among the time-dependent issues addressed are the time scales for startup and shutdown as determined by current profile relaxation rates (skin times), fueling and particle pumping rates, and auxiliary heating and current drive sources. Operational constraints are monitored throughout the simulations: βt, ℓi, , ne(a), etc.
